PAGE 1 OF 5, WHAT IS MOMENTUM?
MOMENTUM DEFINED

THE POWER OF MOTION
Imagine two bowling balls rolling toward you. One is slow and heavy. One is fast and light. Which one is harder to stop? The answer reveals momentum! Momentum is not just about speed. It's about mass times velocity—the marriage of how heavy something is and how fast it's moving. A slow, massive truck has tremendous momentum. A fast, light bullet also has tremendous momentum. Momentum = Mass × Velocity. This quantity is what keeps things moving forward and what makes collisions so powerful.
📐 THE FORMULA
p = m × v (momentum equals mass times velocity)
DRIVE!
SLOW MASS
Comic illustration: THE POWER OF MOTION, SLOW MASS
🚚 Heavy truck rolling slowly
→ Hard to stop due to mass
⚖️ Big momentum!
FAST LIGHT
Comic illustration: THE POWER OF MOTION, FAST LIGHT
🚀 Fast bullet moving rapidly
→ Hard to stop due to speed
⚖️ Big momentum!
